At the end of the rope

My husband added a female coworker. She has a boyfriend but she likes his stuff a lot and sent him a random weather article. He won’t delete her because he said that would make it look like hesbeing mean but it’s ok to keep her on there and have it look like something is going on? We have argued about this for like 10 hours he withheld sex from me last night made me sleep downstairs and then when I woke up he told me to give him a blowjob. We tried to have sex and he was just being so condescending I started bawling and he said I can’t do this you’re so jealous I want a divorce

....yet nothing is going on with this girl??!
